TRAYSLUOEN'I L'UMINOUS ADVERTISING MIRROR.

Application filed March The present invention relates to.a trans.

lucent luminous advertising mirror, the advertisement band of which is intermittently controlled and intermittently illuminated by electromagnetic means. I

For allowing that the duration of the nterval may be accurately regulated at will, the present invention provides besides the electromagnet controlling the advertisement band, a second electromagnet connected therewith, the displaceable iron core of which second electromagnet has at its lower end a piston, moving in a pneumatic cylinder serving as a brake, and having at its upper end a contact plate, so that when the current is switched on, the piston will, correspondingly to the resistance of the air be slowly forced upwards by the electric magnet and the contact plate lifted, and retained in such position until the two electromagnetsare again switched ofi, after such switching off the piston slowly sinks until the contact plate has again reached the contacts and thereby again switches the electromagnets on. The duration of the break may be regulated by re ulating the pneumatic resistance in the cy inder, for example by turning a regulating screw provided in the same.

In the accompanying drawings a constructional form of the present invention has been exemplified. V

The electromotor 2 fitted to thecasing 1' drives the shaft 3, the worm 4 and the worm wheel 5. wheel carries a bevel gear 6, with which mesh the bevel gears 7' and 8.v The bevel gear 7 is fitted loose on its shaft 9 to the end of which is displaceably fitted the coupling sleeve 10. When this sleeve is forced against the bevel gear 7 it engages withthe coupling member 11 of the bevel gear 7, so that the shaft 9 is driven.

To the free-end of the latter is fitted a sprocket 12 which by The horizontal shaft of the worm means of achain 13 drives the sprocket 14 and the roller 15. Thereby the advertisement band 16 iswound onthe roller 15. Opposite to sleeve 10 a sleeve 18 is displaceably fitted on shaft 17. When-this sleeve 18 is approached to the bevel gear 8, running loose on its shaft, the shaft 17 is rotated and with it the sprocked 19, which by means of chain 20 drives the sprocket 21 and the upper roller 22, which winds up the advertisement band at the top. The sleeves 10 and 18 have each a collar 23 and both collars are engaged by a fork 24 disposed behind them. The fork 24 is pivoted-on a pin 25 and is made in one piece with the lever 26. To the bifurcated'free end of lever 26 is hinged a rod 27, the other end of'which is linked to a double-armed lever 28. The lever arm above the pin 29 is hinged to the iron -core 30 by means of a screw 31. Accordingly as the current is switchedon either the coil 32 or 33 is excited; thereby the clutp h 10 or 18, respectively, is so engaged: that either the lower roller 15, or the upper roller 22, respectively, is rotated for winding the band. For the intermediate position of the lever 28 to be accurately maintained while the coils 32, 33 are switched oif, a horizontal bar 34 is provided over the said coils, in which bar-pins 35, 36 are fitted. Against pin 35 bears a rubber-washer 37, and against pin 36 a rubber washer 38. Springs 39 elastially press the rubber washers against said pins. The end of lever28, extended above To the rearof lever 28 is fitted a part 40 forming an extension thereof, which together with the lever extension in front of the rod 34 forms a fork, engaging said rod. This part 40 is provided at the rear with a horizontal pin 41 made of fibre. Above this pin a contact 42 is fitted to the casing 1, against which contact bear two contactsprings 43, pivoted on pins 44 and drawn by a tensile spring 45 against the contact 42. The two contact springs close the lamp circuit as long as they contact jointly with the contact member 42. For switching off the lamp it is suflicient to remove one of the springs from the contact member 42. This removal is efiected each time the clutch is engaged, as then the lever 28 forces off by part 40 the one or the other of the said springs 43.

Beside the cou ling coils 32, 33 a coil 46 is vertically fitte to the casing (Figs. 1, 2,

and 5-7) and beneath this coil 46 a cylinder 47 is fitted. A rod 48 is disposed to rise and fall in both, and within the coil said rod carries an iron core, in the cylinder a piston. When the coil 46 is excited, the rod will rise, because the core will be drawn into the coil. When the coil is switched off, the rod will descend,but very slowly, as the piston will have to force the air beneath it out from the cylinder through a small vent, regulable by means of screw 49. To the upper end of rod 48 is fitted an insulated contact plate 50. As soon as the latter sinks with the rod, it contacts with the contacts 52 on the fiber plate 51, and thereby closes the circuit.

Beneath the windmg roller 22 a switch is.

provided at the left side (Figs. 1-4). This switch consists of the double-armed lever 53 pivoted on a screw 54. The upper end is drawn backwards by spring 55, whereby the lowerend, carrying a fiber roller 56 is forced forward. The double-armed lever has about its middle the contact arm 57, which, when the lever 53 is moved, rocks towards or away from the contact member 58. As the roller 56 lies in the ath of the bars 79 of the advertisement ban the latter will intermittently and thereby swltch off the current.

On the right side of the casing is disposed beneath the winding roller 22 a switch for the excitersof the electric magnets 32, 33 for operating the clutch 10, 18. This switch is intermittently reversed by the bars of the advertisement band, namely by the first and by the last for reversin the Winding on. rollers 15, 22. This switch (Figs. 8-11) consists of a casing, 59, which is pivoted on a pin 60. On the inner side of the casing is fitted an insulated contact arm 61, which according to the manner in which 1 it is set, or the casing is set, will form a bridge over the contact arms 621/64 and 64/63. The oscillation of the casing is lim ited by "the yoke 65 through the mlddle of ress the roller backwards,

is fitted to shaft 69, which brake member will switch off the current for one moment in such a manner, that the picture will not go beyond the brake member and willnot be torn. The brake member projects with its point into the casing. In front of this point a slide 71 is disposed in the casing, which is wedge shaped towards the said point and is held pressed against the brake member by means of spring 72. To the front of the casing is riveted a in 73, which, when the casing 59 rocks, Wlll glide with its inner, flattened side over the rectangular face of the brake member. In the middle of the rectangular face of the brake member is provided a recess 74. In each of the side walls of the casing is provided a slot 75 through which passes the shaft 69. \Vhen the lug 76 (Fig. 8) fitted to the bar 79 of the advertisement band engages the pin 73, the casing 59 will rock over and in consequence of such rocking of the casing and the brake member the switching of levers 61/67 will be effected extremely quickly against the action of the slide 71 which is thereby temporarily pushed back. The contact levers, besides, will not stop half way, but will always be forced into the full contact position and there retained. A last switching means is the coil 77, the electromagnet of which attracts the lever 78 rocking on the pivot 80. Thereby the contact 78/81 is closed, and the coil 46 is switched on. After the current has been switched off, the lever 78 will, by its own gravity fall back into the position shown in Fig. 2.

In the diagram Fig. 12.also the connection of the resistances has been included, which must be employed when, instead of 110 volts, a higher pressure, say 220 volts is employed. The resistances are preferably are used namely switch 82 for the reversing switch,-83 for the air cushion and the magnet coil, 84 for the lamps and 85 for the motor. By means of the plug contact 86 the device may be connected with an existing circuit.

The modus operandi of the invention is as I follows w Upon closing the switch 86, a circuit will be completed to the motor 2, continuously rotating the same. he switch 57 bein normally'closed. will. at the same time. e

the motor driven gear 7. This clutch 10 being keyed to the shaft 9, will rotate the same, and thereby rotates the rollers 15 and 22, causing the curtain to move downward until a display registers with the window.

'At this time, a projection on the curtain striking the roller 56 will break the circuit through the switch 57, allowing the lever 28 to swin to a central position thereby disengaging the clutch 10 and simultaneously completing the circuit to the lights throu h the switch arms 43. At the same time, tie solenoid 77 being deenergized, the circuit through the contacts 78 and 81 will be broken, thereby deenergizing the solenoid 46 and allowing the piston to settle slowly in the dash pct 47 until the switch 50 closes and completes a circuit through the switch 6 to the solenoid 32, causing the same to switch of]? the lights and again start the curtain in motion and allowing the switch 57 to again close. After this, the operation will be repeated until the curtain becomes com letely unrolled from the roller 22, at

-Icaim: i.

whic time, another projection on the curtain will cause the switch arms 67 and 61 to break the circuit to thesolenoid 32 and to complete the circuit to the solenoid 33, cansing the clutch member to engage the gear 8 and reverse the direction of rotation of the rollers. The curtain becoming completely unrolled from the roller 15, another projection will cause the switch arms 67-and 61 to position, thus repeating the'o eration.
